TAKE UP MECHANISM FOR LOOIWS.

SPECIFICATION forming part of Letters Patent No. 392,086, dated October30,1888.

(No model.)

To aZZ whom it may concern:

Be it known that we, AUGUST WIERTZ and CARL HAUSMANN, of the city of NewYork, in the county and State of New York, have invented certain new anduseful Improvements in Take-Up Mechanism for Looms, of which thefollowing is a specification.

The object of our invention is to provide a new and improved attachmentto looms for the purpose of automatically regulating and governing thedistance the cloth-beam is rotatedfor each pick.

The invention consists in the construction and combination of parts anddetails, as will be fully described and set forth hereinafter, and thenpointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of a loom providedwith our improved attachment, parts being broken out and others being insection. Fig. 2 is a sectional plan view of part of the same.

Similar letters of reference indicate corresponding parts.

The batten A, carrying the shuttle-race A, both of the usualconstruction, is pivoted to the loom-frame B at B and is connected bythe connecting-rod O with the fiy-wheel G of the driven shaft D of theloom. The bar E is pivoted at one end to the batten, and at the otherend it is provided with the longitudinal slot E, through whicha pin, F,passes freely from the upper end of a rocking lever, G, pivoted at itslower end to the frame of the loom. The bar Z is guided to reciprocatehorizontally, and is provided at one end with the longitudinal slot H,in which the pin J is held adjustably by a nut or other suitabledevicethat is, in such a manner that it can be moved toward either endof the bar. A roller, K, is pivoted in that end of the bar Z oppositethe one provided with the slot, said roller being adjacent to one of theribbon-pulleys L on the cloth beam M. A weight, 0, is suspended by meansof a cord from the bar Zfor the pur pose of producing friction toprevent the bar from moving too freely.

On the end of the cloth beam M the cogwheel a is fixed, and engages thepinion b on the shaft 0, carrying the cog-wheel d, engaged with thepinion e on the shaft f, carrying the ratchet-wheel g, with which thespring-actuated pawl P on the rocking lever Q engages. A spring, R,draws the rocking lever Q down ward, and the swinging end of said leveris connected by the cord S, passed over the pulley T, with the rockinglever G.

W is the check-pawl for the ratchet-wheel.

As shown in Fig. 2, the pin J projects such a distance from the bar Zthat the lever G can come in contact with it.

We have shown our attachment applied to a ribbonloom; but it is evidentthat it can be applied on any other loom as well.

The operation is as follows: The pin J is adjusted in the slot H of thebar Z accordlng to the number of picks desired to the inch. For eachpick the lever Gis swung once, and dur ing one part of its stroke itpulls the cord S 1n the direction of the arrow 00, whereby the leverQisswung up and, by means of the springactuated pawl and the gearing,rotates the clothbeam slightly in the direction of the arrow as",whereby a certain quantity of fabric 1s wound on the cloth-beam orpulleys thereon. The lever G can only swing in the inverse direction ofthe arrow 00 until it strikes the pin .J, which checks it. The bar Econtinues to move in the inverse direction of the arrow at, the pin Fmoving freely in the slot E. As the diameter of the roll of fabric onthe clothbeam, or the pulleys L thereof, increases, it pushes the rollerK and the barl in the direction of the arrow 00, and thus the pin J isgradually moved nearer the leverGand gradually shortens the swing of thesame in the inverse direction of the arrow x. As the distance of theswing of the lever G in the inverse direction of the arrow 00 decreases,the swing of the pawl-lever Q decreases, and thus the pawl P grips lessteeth of the ratchet-wheel g and the cloth-beam is rotated less. The increase in the diameter of the roll of fabric on the cloth-beam thusautomatically shortens the distance of rotation of the cloth-beam foreach pick.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. The combination,wit h a loom-frame, batten,and clothbeam, of the rocking lever G, connected with the batten, thebar Z, having one end adjacent to the cloth-beam and pro- ICO vided inits opposite end with the slot H, the

pin J in the slot H, the pawl-lever Q. the cord v S, connecting saidpawl-lever with the rocking lever G, the ratchet-wheel g, engaged with 5the pawl on the pawl-lever, and gearing for transmitting motion from theratchet-whee] g to the cloth beam, substantially as herein shown anddescribed.

2. The combination,with a loom-frame, bat- IO ten, and cloth-beam, ofthe rocking lever G,

having the pin F, the connecting-bar E, having the slot E, the bar Z,provided at one end with the slot H, the pin J in said slot, the

roller K on the other end of the bar Z, which 15 roller K is adjacent tothe clothbeam, the
